HEATER.

Application filed. January My invention relates to heaters and has for its object the provision of an improved stove with a relatively large radiation surface so formed as to direct a. large proportion of the radiated heat horizontally. It has for a further object the provision of a stove containing an improved heat resisting horizontally serrated core whereby the hot products of combustion are guided into contact with correspondingly serrated radiator side walls. It consists also in providing: a stove in which the major part of the side walls above the fuel chamber may be opened outwardly to give full access to their inner faces and to the outer face of said core for the purpose of cleaning or repairing the same. With these and other objects in view, it consists of the structures. combinations, and arrangements of parts hereinafter described and claimed.

In the drawings, Fi 1, is a central vertical section through a stove embodying my said invention. Fig. 2, is a top plan view of the same. Fig. 3, is a top plan view of the same showing the side walls in open position, and Fig. 4, is a front elevation of said invention.

In the drawings, 1 is a base containing an ash chamber 1, and a fuel chamber 1 which ash chamber is adapted to be closed by a clean-out door 2 and by any suitable the door 3. A fueling door 4 is provided for said fuel chamber in which door is preferably positioned a ventilator as 5. Said base also contains a grate of any suitable structure, as .6. EX- tending above said base are serrated or corraga-ted side walls, the lower end 7 of which is preferably stationary and formed or erected upon said base, and the upper or major portions of which, as 7 and 7 are adapted to open outwardly and are preferably pivoted upon a post 8. Said side walls are so corrugated, serrated or indented as to present the appearance of a series of superposed funnel shaped sections wherein the upper face of each section is horizontal and the sides of each section incline downward and inwardly at approximately forty-five degrees. Said portions 7 a and 7 are divided from each other adjacent to said post and at the opposite side of the stove from said post, and at their opposing edges are provided with overlapping lips or flanges as 7, 7.

Supported in any suitable manner within 7, 1926. Serial No. 79,876.

the chamber formed by said side walls, is a heat resisting core of any suitable structure or material, as a metal shell 9, filled with asbestos 10, the sides of which are corrugated to correspond with and extend parallel to the corrugations in the inclosing; side walls 7, 7 and 7" from which the de walls of said core are spaced a short distance so as to form a thin annular flue 11 between said core and said inclosing walls, whereby the hot products of combustion. are guided into direct contact with said inclosingr walls, and especially with the horizontal faces thereof. In Fig. 1, of the drawin the space between the core and the inclosingr walls 7 and 7 is broadened in order to more clearly show the several parts. Plaid core may be supported in any suitable manner, as by lugs or pins 12 extending from said base or from the station ary portion of said side walls.

Supported in, any suitable manner above said core, as by posts 13, mounted on said core is a stationary chimney pipe connection 14 preferably provided with a flange 14- corresponding in diameter to the opening at the upper ends of said side walls. Thus when the side walls are opened as shown in Fig. 3, the chimney connection will be sup ported by said core. Said flange and side walls are provided with lips, as 1d and 7 respectively, adapted to overlap in operative position.

When said side walls are closed, they may be held together by any suitable means, as by hooks 15 mounted upon one of the sides and adapted to engage lugs 16 upon the other of the sides.

If desired, polished reflector plates 17 may be secured in any suitable manner to any or all of the outer inclined faces of said sides to more effectively reflect the heat radiated from the horizontal faces of said sides and direct it horizontally. But if desired said polished reflectors may be omitted.

I am aware'that stoves or heaters with corrugated sides are old in the art, but I am not aware of any in which the corrugations or indentations present horizontal surfaces opposed by surfaces directed at an angle of substantially forty-five degrees whereby heat fronr said horizontal surfaces is reflected and directed by the inclined surfaces in a horizontal direction. Nor am I aware of prior stoves with corrugated sides in which alternate faces of the indents are horizontal and in which a correspondingly indented or corrugated core is adapted to guide the hot products of combustion into direct contact with the interior sides of the horizontal faces of said side walls.

What I claim is: I

, In a heater, the combination of a base containing a fuel chamber; a core extending above said fuel chamber; means for supporting said core; side Walls comprising a stationary portion extending up from said base and movable portions extending up from said stationary portions; a post adapted to pivotally support said movable portions; a chimney pipe extending above said core and provided with a horizontal flange; means for supporting said pipe; said IHOV- HUTCHIN SON L.
